UNITED STATES ARTHUR I. ERICKSON, OF PORTLAND, OREGON.

VALVE.

Application filed January 31, 1924. Serial No. 689,654.

My invention relates to valves in general, and particularly to electrically operated valves, the object being to provide a valve that maybe operated by electric push buttons or similar devices, and that may be partially opened, completely opened, or closed by operating a push button respective to the operation desired at the valve.

I accomplish this object by means of the construction illustrated in the accompanying drawing, which is a part of this application for Letters Patent, like characters of reference indicating like parts throughout the several views therein, and in which:

Fig. 1 is a sectional elevation of my demm.

Fig. 2 is a fragmentary enlarged view of the upper end of the valve stem.

Fig. 3 is an enlarged view of the stem retaining spring.

In general my device consists of a valve of the globe valve type with a ball valve -cooperating with a metal seat therein; a pair of axially alined solenoids mounted within a gas tight casing secured to the body of the valve; a valve stem projectingthrough said solenoids; a plunger common to both solenoids and mounted upon the valve stem; yieldable toggle mechanism within said casmg and connected with the valve stem to accelerate .the movement of the same and to hold the same at either end of its path of travel independently of the solenoids; a third solenoid surrounding one of the previously mentioned solenoids and adapted to partially open the valve, and a sprin adapted to.

retain the valve in such partial y open condition.

The valve body, 3 is preferably of the globe valve type as shown, having a ground metallic seat 4 upon'wvhich is seated the ball valve 5. Said ball valve is freely mounted upon a valve stem 6 sothat it may have a limited movement in all directions independently of any movement of the stem. I accomplish this by soldering, or'otherwise securing, a flange 7 upon the ball valve 5, and securing said flange to the stem 6 by means of a pin 8. The stem 6 is a loose fit within the flange 7, and the pin 8 is a loose fitwithin the stem 6, and thus the ball'valve 5 is allowed a limited movement independently of the stem 6.

Mounted upon the valve body, by means of a nut 9, is a plug 10, which fits the valve body with a gas tight ground joint, preferably conical, as shown in Fig. 1. A centrally disposed tube 11 is secured to the plug 10, and is axially alined with the seat of the valve 5, and extends above the plug 10. An outer shell '12 surrounds the tube 11 and is spaced apart therefrom. Said shell is secured to the plug 10 in a gas tight manner. This is accomplished preferably by making the shell cylindrical in form and providing a flanged or disk washer at the lower end thereof, said shell and washer being soldered together, and said washer being soldered. upon the plug 10.

A pair of axially alined solenoids 14 and 15 are disposed within the shell 12 and surrounding the tube 11, and the valve stem 6 passes upward through said solenoids to terminate above the same in a grooved end as shown in Figs. 1 and 2. These solenoids operate respectively the closing and the partial opening of the valve,ias hereinafter to be described. A third solenoid is provided surrounding the upper solenoid 15, as shown at 16, for the purpose of fully opening the valve. Thus. there are three coaxial solenoids, one to open the valve partially, one to open it fully, and one to close it.

These solenoids are provided with a common plun er which is of tubular form as shown at 1 and which is secured to the valve stem by a in 18.

The she I 12 extends beyond the solenoids to form a chamber, preferably at the upper end thereof, as shown in Fi 1, and with-- in such chamber is dispose the yieldable toggle mechanism, and also a spring device for retaining the valve in partially opened position. The toggle mechanism consists of a pair of toggle arms 19 coacting with the slot at 'the upper end of the valve stem and having yieldable fulcrum brackets 20 secured upon an insulating diaphragm 21, which diaphragm closes the shell 12 above the sole-- noids 15 and 16', and forms the bottom of the chamber within which the toggle mechanism is disposed. An electrical contact member 22 is mounted upon the diaphragm 21 and is adapted to contact with one of the toggle attaching a signal lamp 28 as hereinafter described. Said terminal 27 is provided with means for cooperating with one of the toggle arms 19, conveniently being an arm 29 with a contact point adapted to contact with a similar point upon said toggle arm.

A cover 30 is provided for the shell 12, and said cover is provided with a binding post 31 to which to attach a battery or othersource of electrical energy. Push buttons 32, 33, and 34 operate solenoids 14, 15 and 16 respectively through circuits hereinafter described.

To secure the valve stem in position opening the valve partially I provide a cam-like groove 34 therein which cooperates with a vhair-pin spring 35 secured upon the diaphragm 21. When the valve is closed said spring contacts with the head 36 of the valve stem above said cam-like slot 34; when the valve is partially open the spring lies within said cam-like slot 34 and holds the valve in partially open position; when the valve is fully open the spring contacts with the valve stem 6 immediately below the cam-like slot 34; and'when the valve is closed the spring returns to its initial position on the head 36. The sides of the cam-like slot 34 are sufiiciently sloping to allow the passage of the spring from one position to another without undue friction.

The operation of my device is as follows.

Let it be assumed that it is desired to open the valve partially. Then closing push button 33 closes a circuit from the battery 38 through wire 39, push button 33, wire 40, binding post 23, wire 41, solenoid 15, contact 22, toggle arm 19, valve stem 6 which is grounded to the structure, binding post 31, and wire 42 to the battery. This energizes the solenoid 15 and opens the valve until the spring 35 enters the cam-like slot 34. The

strength of the solenoid 15 and of the spring 35 are so relatively proportioned that the spring retains the valve stem 6 against further pull of the solenoid, and thus the valve remains partially open.

If then,it is desired to further open the valve to its fullest extent, push button 34 is closed. This establishes a circuit from the battery 38 through 'wire 39, wire42, push button 34, wire 43, binding post 24, wire 44, solenoid 16, grounded wire 45, and through the structure to binding post 31, and wire 42 to the battery. This energizes solenoid 16 and thus causes the full opening of the valve, the toggle arms .19 assuming the dotted position shown in 1, and thus holding the valve open.

VVhen it is desired to close the valve push button 32 is closed, thus establishing a circuit from the battery 38 through wire 39, wire 46, push button 32, wire 47, binding post 25, wire 48, solenoid 14, ground at 26, through the structure to the binding post 31, and wire 42 to the battery.

This energizes the solenoid 14 and causes the strengths of the solenoid 14 and the spring 35 are such that the solenoid cause: the valve stem to pass the cam like slo. 34 past the spring 35. This also happens when closing the valve.

An indicator light 28 is provided to show when the valve is open. When the valve is open a contact point 50 upon one of the toggle arms 19 contacts with a similar point upon an arm 51, and thus closes a (3111311117 from the battery 38 through wire 42, terminal 31, cover 30, shell '12, base 13, tube 11 and its top closure plug, armature 17 as it contacts with said closure plug, pin 18, stem 6, toggle means 19, contact 50, contact member 29, terminal27, wire 53, signal lamp 28, and Wire 52 to the battery. Thus the light 28 will be lighted when the valve is 0 en;

My device may be made of any size, and constructed of any materials deemed convenient and suitable for a device of this character, and while I have illustrated and described a form of construction and arrangement of parts found desirable in materializing my invention, I wish to include ing; a third solenoid surrounding one of said axially alined solenoids, a plunger common to all said solenoids, a valve; a valvestem operated by said solenoids;'y.ieldable toggle mechanism mounted within. a chamber formed by a prolongation of said casing beyond said solenoids; an electric contact member cooperating with one of said toggle arms and connected to the upper of said axially alined pair of solenoids; ground connections for the lower of said pair of axially alined solenoids and said third solenoid;

within said casing for closing said valve;

' cooperating with said electrical mechanisms to operate said valve; and mechanlsm to resnap acting mechanism within said casing tain said valvein partially opened position.
